Re: Cakephp Ajax helper or Jquery?
Hi Sam,
Progressive enhancement is a very elegant solution for Ajax and UI.
Build your app without any Ajax/JavaScript. Use the app controllers before
filter to change the layout on ajax requests.
public function beforeFilter() {
if ($this->request->is('ajax')) {
$this->disableCache();
$this->layout = 'ajax';
}
}
Ajax requests end up looking something like this.
$.ajax({
data: $form.serialize(),
method: 'POST',
dataType: 'html',
url: $form.attr('action'),
success: function (html) {
var $html = $('').html(html);
// do whatever you want with the returned chunk of html
// example: grab the flash message and fade it in
// make a chicken titty dance
}
});
Used to-do ajax similar to the Rails convention by sending JavaScript to
the browser from a separate view template. Most people find progressive
enhancement so much easier to maintain and it makes front end people happy.
Another tip is to attach your JavaScript handlers to html5 data attributes
instead of css selectors. It's another separation and makes things even
easier to maintain.

Re: How to do recursion more than 2 levels deep using the one table?
Thanks Andre
Unfortunately tree behaviour doesn't really work for my situation as I need
the ability for a node/resource/object to have multiple parents.
I believe the problem is related to using the one model. For eample if I
set up a data model like Country->State->City->Suburb->Street with join
tables the recursion works fine.

localhost:8080/ does not direct to expected page
Dear All
I started using the CakePHP (2.3.5) with Apachec 2.2 as the WebServer.
I am observing one problem, that http://localhost:8080/ does not direct to
the specific page I have routed in route.php.
(A) In route.php, I have added this as my first route:
Router::connect('/', array('controller' => 'welcomes', 'action' =>
'index'));
(B) What I observe that if I change the same route as below:
Router::connect('/welcome', array('controller' => 'welcomes', 'action' =>
'index'));
then with the url: *http://localhost:8080/*
